Specification of Letters Patent.

Patented July 19, 1921.

Application filed July 18, 1917. Serial 10. 181,216.

To all whom it may concern:

Be it known that CALVIN D. CRANE, citizen of the United States, residing at Dayton. in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Liquid Cooling and Aerating Devices, of which the following is a specification.

My invention relates to distillation apparatus and more particularly to an aerator through which the distillate is finally discharged in order to incorporate or entrain a normal quantity of air therewith to relace the air eliminated from the liquid during the process of distillation.

While the invention is particularly ap plicable to water stills for aerating or restoring distilled water which is otherwise possessed of a flat disagreeable taste, it is also applicable to other distillates tor lar purposes.

The object of the invention is to improve the structure, as well as the means and mode of operation of such devices, whereby they will not only be cheapened in construction, but will be more efiicient in operation, positive in action, automatic and unlikely to get out of repair.

A further ob' t of the invention is to provide means or discharging the product of distillation in minute uantities and subseqnently breaking or fine y subdividing said minute quantities to eflect a thorough aeration or entrainment of particles of air.

A further object of the invention is to provide means for eonfining the finely subdivided particles or mist produced by the breaking up or disintegration of the fluid body and again collecting these subdivided particles after aeration in a suitable reservoir. or collector.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the fie'aturesof construction, the parts and combinations thereof, and the mode of operation, or their hereinafter described and set orth in the claims.

Referring to the drawings, Figure 1 is a side elevation of the assembled apparatus forming the subjectmatter hereof. Fig. 2 is a vertical sectional view thereof on line 2-2 of Fig. 3. ii-is a transverse sectional plan view on line 3--3 of Fig. 2.

Like parts are indicated by similar charuivalcnts as I per portion of the housing 1 is a chamber or compartment 7 into which discharges an inlet conduit 8 leading from the distilling apparatus. The bottom of the compartment 7 18 provided with a series of openings arranged preferably, though not necessarily, in concentric series. Suspended within the openings of the bottom of said compartment or chamber 7 are a plurality of pendant tubes 9 contracted or tapered at their lower ends as indicated at 10 and flanged as at 11 at them upper ends for engagement with the bottom of the chamber 7. As shown in Fig. 3 these pendant tubes are arranged in two concentric The lower tapered ends 10 of the tubes are provided with minute discharge orifices through which the distillatewhether same be water or other fluid, Wlll drip. The product of distillation d scharged into the chamber 7 through the inlet conduit 8 fills said chamber 7 and the pendant tubes 9 which communicate with said chamber 7 and is fed slowly from said tubes through the minute perforations in the lower tapered ends thereof.

Resting upon the base plate 4 of the structure is a flanged receiving pan 12 having a discharge faucet 13. Inter sed between the main housing 1 and the ange or shoulder of the flanged pan 12 is a sleeve or cylindrical inclosure 14 of perforate material preferably, although not necessarily, a finely woven Wire mesh fabric. Positioned within the perforate inclosune 14 in per dicular almement with the discharge ori cos of the respective series of pendant tubes 10 are imperforate bafiles 15 and 16. These batlies 15 and 16 are preferably annular in form and are positioned to receive the drip or discharge from the perforated terminal ends of the pendant tubes 10. These annular baffles 15 and 16. may be supported upon radially disposed wires or spider arms secured to t e perforate side walls 14 of the intercepts the liquid particles.

inclosure or may be supported upon diaphragms 17 of similar perforate or mesh ma terial. The water or other product of distillation discharged through the minute openings in the lowerends of the pendant tubes 10 falls by gravity upon the baffles 15 and 16 from the tubes of the respective series. The impact of the drops or stream of liquid, as the case may be, upon such baffles, causes the liquid to splash and is thus broken up or disintegrated into fine particles which inactual operation produce a variable mist. During the passage of the water from the discharge orifices of the pendant tubes to the batlles a quantity of air is entrained therewith. However, the breaking up of the liquid body by its impact upon the baffies and subsequent splashing in several directions further increases the entrainment of air particles. The splashing particles of liquid will be intercepted by the perforate walls of the inclosure 14 which, while permitting a free circulation of air, effectually The liquid particles will be collected upon the perforate or mesh walls of the inclosure l1 and will trickle down said walls to the collecting pan 12. Other particles of water which fail to reach the exterior walls 14: of the inclosure will trickle through the perforate diaphragms 17 or will overflow the baffles 15 and 16 and in dripping from one baffle to the other orfrom the upper diaphragm to the lower and thence to the collecting pan 12, will become thoroughly aerated. The passage of the product of distillation in small quantities from the chamber 7 through the body of air contained in the perforate inclosure' 14 to the receiving pan 12 not only aerates the liquid and facilitates the entrainment of air, but it alsoserves to cool the product of distillation, bringing each minute particle of the fluid into direct contact with the air body by which the entrained heat is dissipated.

The flanged upper ends of the tubes 10 are fixedly united to the bottom of the chamber 7 by soldering, electric weldin brazing or other suitable means. The pen ant tubes 10 thus become for all practical purposes, integral parts of the chamber 7. The main housing 1 is provided with a removable cover 19 to facilitate the examination and cleansing of the chamber 7 and the pendant tubes 10. The projecting flange 12* of the collecting pan 12 servesto collect any particles of fluid which may pass through the perforate or mesh inclosure l4: and trickle down the outside of said perforate walls. The fluid so collected is returned to the collecting pan 12.

From the above description it will be apparent that there is thus provided a device of the character described, possessing the particular features of advantage before enumerated as desirable but which obviously is susceptible of modification in its form, proportion, detail construction or arrangement of parts, Without departing from the principle involved or sacrificing any of its broadly in any of its possible forms or modifications within the scope of the appended claims.
